Massey-Harris Model 101

[1] Developed under the guidance of James S. Duncan, who gambled corporate losses would drop and won, the 101 introduced the Chrysler L-head inline six.

The six would compete with Oliver's straight-six Model 70, while saving money on development of a whole new engine as well as taking advantage of Chrysler's existing parts and service network.

[1] Run at much lower revs than the truck engine, the 101 came in the usual standard and row-crop models, with four-speed transmission, and was capable of 20 mph (32 km/h) on roads.

[3] The Super was upgraded to the 217 in³ (3,554 cc) Chrysler in 1940,[1] giving it almost 50 hp (37 kW) at the belt, making it one of the most powerful tractors on the market that year.

The Junior, comparable to the Deere Model H,[8] used the same 124 in³ (2,031 cc) engine of the later 81 and 20,[5][9] and produced 31 hp (23 kW) at the belt,[10] Manufactured by Continental, it was used in many Massey Harris tractors at the time,[6][9] as well as by the Cockshutt 20 and Oliver Super 44.
